formerlySteel storage that gets in where containers can't.
Modular steel self-storage units, garden stores and site buildings. They arrive as a kit, go through a side gate or down a tight yard, and are built on site with no crane.
Only the name has changed.
Steel & Storage started with one idea: a better steel unit than a shipping container. Our range now covers storage units, garden stores, insulated rooms and site buildings, so we've given it one name: B0XD, for Intelligent Modular Space Solutions.
Spelled with a zero: B-0-X-D. The X doubles as an open box, lid and all.
Build your unit.
Choose the width, length, door position and colours. The drawing updates as you go. Turn on the container outline to compare the two.
A shipping container only opens at the end. Our doors go on whichever side faces your drive or aisle.
B0XD units vs shipping containers
We still supply new one-trip shipping containers. Where access, planning or condensation matter, this is why customers choose our modular units instead.
| B0XD modular unit | Shipping container | |
|---|---|---|
| Getting it in | Arrives as panels and goes through a side gate by hand | Needs a clear route for a lorry plus a HIAB or crane |
| Doors | 1,750 mm double doors on the short end or long side | End doors only |
| Height | Under 2.5 m | 2.59 m |
| Condensation | StorDri-lined roof as standard on self-storage units | A common problem with bare steel |
| Colour | Any RAL colour, factory powder-coated | Repainted on site |
| Sizes | 2 m to 6 m long, 2.1 m or 2.3 m wide | Fixed 10, 20 and 40 ft |
| Planning | Looks purpose-built, which helps beside houses | Often resisted |
| Moving later | Freestanding, so it can be taken down and rebuilt | Needs another lift |

How many units fit your yard?
Enter your yard size for a rough count. Our site design service then lays out your space for the most units and gives you an interactive 3D walkthrough before you order.
Use − and + to set how many of each size you want compared with the others. 0 leaves a size out. Shipping containers only open at the end.
1.5 m suits walk-in corridors. Allow about 6 m for drive-up access.
A rough guide using XL units (2.3 m wide) and standard 2.44 m wide containers in back-to-back rows with a 1 m margin around the yard. It doesn't allow for entrances, turning space, fire breaks or planning conditions.
